CULTlVATOR- SPECIFICATION forming part of Letters Patent No. 324,904, dated August 25, 1885.

Application filed August 11,1883. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM S. WEIR, residing atll/Ionmouth, in the count-y of Warren and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Cultivators, of which the following is a full description, reference being had to the accompanyingdrawings, in which- Figure l is a top or plan view; Fig. 2, a side elevation with the wheel removed; Fig. 3, a top or plan view of the draft-frame and beam-coupling; Figs. 4 and 5, details of the wheel-spindles; Fig. 6, an under view of the guide-bar of the wheel; Fig.7, a section on line a; w of Fig. 3, and Fig. 8 an elevation of one end of the coupling bow or arch.

The object of this invention is to improve the construction and operation of that class of cultivators known either as parallel or ton gueless and its nature consists in the improved parts and combinations of parts hereinafter described and claimed as new.

In the drawings, A A indicate the connecting bows or arches; B, the draft frames,- (J, the cross-bars or interior frames of the draftframes; 1), the wheels; E, beams or dragbars; F, coupling-plates; a, sockets for holding the bows A A b, notches or openings in the sockets a; c, pivotal ends of the bows or arches; d, ears for attaching the guide-bars; c, ears for attaching the wheelspindles; f, prongs or forks of the wheel-spindles; g, wheel-spindles; h, projections or teeth on one side of the wheel-spindle fork; i, notches or teeth on the under side of the guidebar; j, guide-bar; k, adjustable plate for connecting the rear ends of the guide-bars with the cultivatorbeains; lm, slots for the plate 70; n, rocking bars or plates across the rear ends of the draft-frames; 0, holes for adjusting the space between the beams; p, plate located between the coupling-plates F, for limiting the movement of the draftfmmes q 1', bolts 5 s t n, pivots, and v draft-hooks.

This cultivator is usually made entirely of iron and steel. The bows or arches A A are by preference made of flat metal bars, and made tlat tOpped, as shown at Fig. 8,but they may have a curved arch, if desired. They are provided at their lower ends with spindles c, which project through the sockets to of the draft-frame. \Vhen the bows or arches are made of round iron, the lower part, or the part next to the spindles or pivots 0, will be flattened to fit into the notchesor openings 1) of the socket a. So much of thebow as onters the socket is made sullicientlly thinner than the width of the notches I) to permit of the desired play at this point, and byinserting the ends of the bows in notches a limit to the forward movement of either beam in refer-.

ence to the other is had, so that when one draft-animal is separately hitched each side it cannot get sufticiently far ahead or far hehind in turning around row ends as to permit the beams to come together, and thus allow the machine to tip over. An arrangement which will allow a ariation not exceeding two feet will be sufficient, and this arrangement will keep the machine spread out as it should be when in operation however unequally the team may walk. The bows are held in place by keys or pins passing through the spindles below the sockets, as shown in Fig. 2. The draft-frames B are made of .wroughtiron, but, if desired, may be made partly or wholly of cast-iron. The frame 0, of which the sockets 6 form a part, is most easily made of malleable iron havingthe outer two bars of the frame B attached to its outer ends. The rear crossbar, (J, is provided with a plate or flange, p, which projects out between the plates of the coupling F, as shown at Fig. 7, and thereby forms the tipping limitof the bows or arches and the draftframe B, as when the draft-frame, with the bows, tips forward its plate will strike the upper coupling-plate, and when in its position for work this plate 19 will be near the lower coupling-plate, as shown in said figure. This arrangement gives ample provision for lifting the rear ends of the plow-beam when a draft animal is hitched to the hook v. The rocking bar a has its ends furnished with pivots, and it is also provided with openings 0, for changing the connection therewith of the couplingplates F, and for this purpose the plates F are provided with projections or ears, which enter the openings or holes 0, as shown at Fig. 7, and form the pivots by which the lateral movement of the plow-beams is obtained, the vertical movement being obtained by the roekin g of the plate or bar a with or by the coupling. The coupling-plates are held to gether by the bolt 1", and by loosening this bolt the coupling-plates may be opened for changing the adjustment. The beams E are made of flat bars, bent as shown, and the bolt r passes between them at the front bend, as indicated in Fig. 7.

In rear of the coupling-plates 1* is located the cross-plate 7.", which is attached to the beam E by an under plate, and the bolt q, the underplate, and the plate It form a clamp. The plate 70 is provided with a slot, l, through which the rear end of the guidebarj passes. It is also provided with a slot, on, through which the bolt q passes, so that when the beam is adjusted the plate 7; may take asimilar adjustment, and thus keep the armj in the same position when the beams are adjusted to increase or diminish the space between them. The adjustment at the slot m may also be used to perfect the adjustment of the arm j in respect to the proper movements of the wheel. The arm j is pivoted to the ear (I of the draft-frame, and, it is understood, is pro- -vided with pins or teeth 2', which gear or engage with pins or teeth h on the head fof the wheelspindles. The teeth i are made a part of or are firmly attached to the guide-arm j, and when in position it is pivoted to the ear cl at t, as shown. The wheel-spindles are pivoted to the ears 0 at s, as shown, so that moving the rear end of the guide-arm j in either direction changes the line of the wheel-spindle and gives the wheel a changed direction, and, as the rearend of the guide-arm passes through the slot 1 of the plate It, it will be evident that whenever the operator moves either beam its corresponding wheel will have its line of progression changed, and that if both beams are moved in the same direction the direction of the entire machine will be changed, so that in throwing the beams around at the ends of rows the wheels will come more readily into position for turning. Moving the beams in opposite directions at the same time will give the wheels different lines of progression but as this so seldom occurs in actual use it is not regarded as a defect, while moving one beam to get around a single plant or obstacle will wheels through their spindles, so as to give them a direction to aid the movement made by the operator, and thus avoid obstacles or get around plants out of line with ease and certainty.

By arranging the forward bow, A, as shown, the whit'tletrees are prevented from coming together by the draft of the team, and they are also prevented from swaying inward or outward, soas to defeat the action of the guide bar or leverj.

What I claim as new, and desire to secure by Letters Patent, is as follows 1. The guiding-lever having the teeth or gear i,in combination with the wheel-spindles g, having the gear or teeth h, substantially as specified.

2. The combination of the guiding bar or lever-j, having the teeth 2', with the pivoted wlieel spii'idle having the teeth h, the plate It, and beam E, substantially as described.

3. The combination of a draft-frame, B, ha"- ing sockets a, slotted at their upper ends, the arch or bar A, flattened adjacent to the sockets,'guide-bars j, pivoted to the draft-frame, spindle-plates], and beaniplates 7c, substantially as described.

4. The combination of the pivoted arches A A, draft-frames B, guide-bars j, having teeth 1 with the pivoted wheelspindles g, having the teeth h, and the adjusting-plate k, substantially as and for the purpose specified.
